IMPROVEMENT IN STEAM-ENGINE LUBRIGATORS.

TO ALL WHOM-IT MAY CONCERIT:l

4Be it known that we, JOHN L. WBIPPLE and AnoLPnUs BoNzANo, of Detroit, in theeonnty of Wayne, and State of Michigan, have invented a new and improvedvLuhricator; and we do hereby oeclare that the'following -is a full,'clear, and exact description thereof, whichvnyillcnable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification'.

This invention relates to a new and improved method for lubricating slide-valves, cylinders, lift-rod, and wearing-surfaces in other situations; and' it consists in attaching to a slide-valve, or other'reciprocating portion of a machine, a rod, which shall have access to oil (or other lubricating material) inv a suitable stationary cup or containing-vessel, whereby the oil is lwithdrawn from the cnp'and deposited upon the wearing-surfaces, as will be hereinafter described. The drawingv y Figure 1, represents the oil-cup and rod attached to the slide-valve of a -steam-engine, it being a vertical section through the line a: :u of'g. 2.

Figure 2 is a plan or top view of the same.

Similar letters of reference indicate like parts.'

A represents a steam-chest;` BY is tllelide-valve, C is the face of the cylinder, D is the oil-clip, and E is the lubricating-rod In this example of our invention, the oil-cup and rod are represented as attachedto the slide-valve of a horizontal engine. This, ot' course, requires a'dierentfformation for the base of the cup than where' the rod is applied to upright engines, orwvertical bearing-surfaces. In the former 'case a tube, lying parallel With'the face of the cylinder, forms the base of the cup, as represented in the drawing. In the latter case the lubricating-rod-E may enter the' cup itself. The oil-cup, in thecase represented, isatta'ched to the steamchest by a tight andpermanentjoint. In the lubricating-rod there may be a holeor holes, which may pass througlror partially through the rod, as seen at a. When the rod is in motion, these holes or cavities fill with oil, as this portion of the rod is passed into thevoiltube or cup, and when the rod is withdrawn, the oil is depositedavithin the chest, and uponV the wearing-surface. I'lhe rod may work loose enough to withdraw the required quantity of oil without any hole or indentation whatever. When thearrangemcnt is applied to'eylinders, either horizontal or upright, the'rod E would work through lthe cylinder-head.

'We are an'are of the patent granted to R. Rafael, September 12, 1865, for boiler-feeder, but' nsthis formsv no part of our invention, we do not, therefore, claim it.

v What We vclaim .as new, and desire to secure by Letters Patent, is A Thel cinbination of the perforated orgindented rod E and oil-cnp'D with the cylinder A and slideelalve I3, substantially :ts-described tor the purpose specified.
